Description

Technical Field

[0001] The present invention relates to the technical field of production equipment, and in particular to a jig distance changing mechanism and a conveying device. Background Art

[0002] During the assembly and processing of battery cells, the battery cells are usually placed in fixtures such as cups and circulated on the production line. In order to adapt to the processing rhythm and other requirements required by different processes, it is often necessary to set up a combination of cylinders and screws to adjust the spacing between fixtures to meet operations such as material diversion and confluence.

[0003] However, the existing variable pitch fixture structure based on pneumatic and screw drive has high requirements on the manufacturing accuracy of the components, and has a complex structure and high cost. More importantly, due to the high accuracy requirements, it is easy to cause material jamming, which in turn affects the smoothness and efficiency of production. Summary of the invention

[0004] The main purpose of the present invention is to provide a jig distance changing mechanism and a conveying device, aiming to reduce the structural complexity and cost of the jig distance changing mechanism and improve the reliability of use.

[0005] In order to achieve the above-mentioned object, the present invention proposes a jig distance changing mechanism for a conveyor line, wherein the jig distance changing mechanism comprises: A rotary damper is arranged at one side of the conveyor line, the rotary damper has a fixed end and a rotating end, the fixed end is connected to the conveyor line, and the rotating end extends vertically and rotates around a first axis; A material dividing piece is arranged at the rotating end, and a plurality of limiting parts are arranged on the side of the material dividing piece. The plurality of limiting parts are arranged at intervals around the first axis. The limiting parts extend to the conveying line. The fixture on the conveying line abuts against the limiting parts and pushes the material dividing piece to rotate to achieve distance change.

[0006] In one embodiment, the limiting portion is configured as a ratchet, and the distance between two adjacent ratchet teeth is not less than the outer diameter of the fixture.

[0007] In one embodiment, the rotary damper is configured as an adjustable damping shaft.

[0008] In one embodiment, the jig distance changing mechanism further includes a counting component, and the counting component is disposed on the material dividing member to count the number of times the material dividing member rotates.

[0009] In one embodiment, the counting component comprises: A counting hole, one counting hole is provided on each of the limiting parts; The counting sensor is arranged above the material dividing member and opposite to the counting hole.

[0010] In one embodiment, the jig distance changing mechanism further includes a stopping component, and the stopping component is disposed on one side of the material dividing piece to block or release the material dividing piece.

[0011] In one embodiment, the stop assembly comprises: A telescopic member, disposed on one side of the material dividing member, the telescopic member having a telescopic end that moves toward or away from the material dividing member; A blocking member is arranged at the telescopic end. When driven by the telescopic end, the blocking member abuts against or separates from the side of the material dividing member, thereby blocking or releasing the material dividing member.

[0012] In one embodiment, the jig distance changing mechanism further includes a bracket, the bracket is used to be connected to the conveyor line, and the fixed end is movably connected to the bracket to move closer to or away from the conveyor line.

[0013] In addition, the present invention also proposes a conveying device, comprising: Conveyor lines; The jig distance changing mechanism is arranged on one side of the conveying line, and the jig distance changing mechanism is the jig distance changing mechanism described above.

[0014] In one embodiment, at least two conveyor lines are provided, and at least two conveyor lines are provided in parallel. At least one jig distance changing mechanism is provided corresponding to each conveyor line, and a connecting port is provided between every two adjacent conveyor lines, and the connecting port is provided upstream of the jig distance changing mechanism.

[0015] In the technical solution of the present invention, the jig distance changing mechanism includes two parts: a rotary damper and a material dividing piece, wherein the rotary damper is arranged on one side of the conveyor line, the fixed end of the rotary damper is connected to the conveyor line, the rotating end can rotate around the first axis, and the rotating end has damping when rotating. In addition, a material dividing piece is arranged on the rotating end, and a plurality of limiting parts are arranged on the side of the material dividing piece to cooperate with the jig; when in use, the jig on the conveyor line will abut the limiting part and drive the material dividing piece to rotate toward the downstream side of the conveyor line under the drive of the conveyor line. Since the rotation of the rotating end has damping, the jig will be blocked by the limiting part and the speed will be reduced until the limiting part rotates to the outside of the conveyor line. At this time, the jig is not blocked, and the jig continues to be conveyed downstream under the drive of the conveyor line, while other jigs upstream will cooperate with other limiting parts to repeat the above action. The distance between the jigs will increase after passing through the material dividing piece, thereby achieving the effect of distance change. In the above structure, the jig pitch changing mechanism does not need to be equipped with a power source. The pitch changing can be achieved by relying on the power provided by the conveyor line and the damping provided by the rotary damper. The structure is simpler than the existing technology, reducing the structural complexity and cost. In addition, during the above action process, as long as the rotary damper itself does not get stuck, the material dividing piece can continue to rotate by relying on the power of the conveyor line, which also eliminates the problem of jamming and improves the reliability of use.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] In order to simplify the jig distance changing mechanism 10 and reduce the cost, the present technical solution proposes a jig distance changing mechanism 10 for a conveyor line 20, and the jig distance changing mechanism 10 includes: The rotary damper 100 is disposed on one side of the conveyor line 20. The rotary damper 100 has a fixed end and a rotating end. The fixed end is connected to the conveyor line 20. The rotating end extends vertically and rotates around a first axis. The material dividing piece 200 is arranged at the rotating end, and a plurality of limit parts 210 are arranged on the side of the material dividing piece 200. The plurality of limit parts 210 are arranged at intervals around the first axis. The limit parts 210 extend to the conveyor line 20. The fixture 30 on the conveyor line 20 cooperates with the limit parts 210 and pushes the material dividing piece 200 to rotate to achieve distance change.

[0024] In the technical solution of the present invention, the jig pitch changing mechanism 10 includes two parts: a rotary damper 100 and a material dividing member 200, wherein the rotary damper 100 is arranged on one side of the conveyor line 20, the fixed end of the rotary damper 100 is connected to the conveyor line 20, the rotating end can rotate around the first axis, and the rotating end has damping when rotating. In addition, the material dividing member 200 is arranged on the rotating end, and a plurality of limiting parts 210 are arranged on the side of the material dividing member 200 to cooperate with the jig 30; when in use, the jig 30 on the conveyor line 20 will abut against the limiting part 210 and Driven by the conveyor line 20, the material distributor 200 is driven to rotate toward the downstream side of the conveyor line 20. Since the rotation of the rotating end has damping, the jig 30 will be blocked by the limit part 210 and the speed will be reduced until the limit part 210 rotates to the outside of the conveyor line 20. At this time, the jig 30 is not blocked, and the jig 30 continues to be transported downstream under the drive of the conveyor line 20, and other jigs 30 upstream will cooperate with other limit parts 210 to repeat the above action. The distance between the jigs 30 after passing through the material distributor 20 will increase, achieving the effect of pitch change. In the above structure, the jig pitch change mechanism 10 does not need to set a power source. The pitch change can be achieved by relying on the power provided by the conveyor line 20 and the damping provided by the rotary damper 100. The structure is simpler than the prior art, reducing the complexity and cost of the structure. In addition, during the above action process, as long as the rotary damper 100 itself is not stuck, relying on the power of the conveyor line 20, the material distributor 200 can continue to rotate, which also eliminates the problem of stagnation and improves the reliability of use.

[0025] like Figures 1 to 3In one embodiment of the present invention, the jig pitch changing mechanism 10 includes a rotary damper 100, which can be a damping shaft commonly found on the market. The rotary damper 100 can be arranged on one side of the conveyor line 20. The rotary damper 100 has a fixed end and a rotating end. The fixed end is connected and fixed to the conveyor line 20, and the rotating end rotates around a first axis. The first axis can be a vertical axis. A material dividing piece 200 is arranged at the rotating end. The material dividing piece 200 can It is a circular flat plate structure. The material dividing member 200 rotates with the rotating end. A plurality of limiting parts 210 are arranged on the side wall of the material dividing member 200. The limiting parts 210 can be recessed to form an arc-shaped groove on the side wall of the material dividing member 200. The plurality of limiting parts 210 are arranged at equal intervals around the first axis. The limiting parts 210 can be rotated to the top of the conveyor line 20 or to the outside of the conveyor line 20. When the jig pitch changing mechanism 10 is working, the upstream jig 30 reaches the jig pitch changing mechanism along the conveyor line 20. 10, the jig 30 can abut against one of the limit parts 210, and the jig 30 has a drive to move downstream under the drive of the conveyor line 20, so that the jig 30 can push the material dividing piece 200 to rotate through the limit part 210. Since the rotation of the rotating end has a certain damping, the speed of the jig 30 moving downstream will be reduced under the combined action of the damping and the force of the conveyor line 20, and then the material dividing piece 200 continues to rotate. When the material dividing piece 200 rotates to the outside of the conveyor line 20, the jig 30 will not be restricted at this time, and will recover to the original speed and continue to move downstream under the action of the conveyor line 20; at this time, another jig 30 upstream can abut against another limit part 210, and continue to drive the material dividing piece 200 to rotate. When the above-mentioned another jig 30 also breaks away from the restriction of the limit part 210, the distance between the above-mentioned another jig 30 and the previous jig 30 has been increased, and the subsequent jig 30 will repeat the above-mentioned action, thereby realizing the variable distance of the jig 30. The present technical solution does not rely on an additional power source, but only relies on the drive of the conveyor line 20 and the damping effect provided by the rotary damper 100 to achieve the distance change of the fixture 30. This design not only simplifies the structure and reduces the complexity and cost of the system, but also reduces the possibility of mechanical failure because there are no additional power components. In addition, since there is no friction between the limiter and the fixture 30, the jamming problem caused by friction is avoided, which significantly improves the reliability and stability of the system operation.

[0026] Figure 3A structural form of the limiting portion 210 is shown. In this solution, the limiting portion 210 is configured as a ratchet, and the spacing between two adjacent ratchets is not less than the outer diameter of the fixture 30; the fixture 30 can abut against the ratchet to achieve speed reduction. In addition, the spacing between two adjacent ratchets can be adjusted according to needs. Generally, the spacing between adjacent ratchets is not less than the outer diameter of the target fixture 30, ensuring that the fixture 30 has sufficient movable clearance to prevent jamming; in addition, this solution adopts the structural form of ratchets, so that the fixture pitch changing mechanism 10 can not only be adapted to the target fixture 30, but also can be adapted to fixtures 30 of other specifications with an outer diameter smaller than the target fixture 30, as long as the outer diameter of the fixture 30 is greater than the spacing from the top of the ratchet to the side wall on the conveyor line 20 away from the ratchet (to prevent the fixture 30 from leaking from the gap between the side wall on the conveyor line 20 away from the ratchet and the ratchet), thereby improving the versatility of the fixture pitch changing mechanism 10. In addition, in order to prevent the jig 30 from being scratched, the side wall of the material dividing piece 200 between two adjacent ratchets may have an arc-shaped transition, and the top of the ratchets may also be provided with a rounded corner.

[0027] In order to further improve the flexibility of use, in one embodiment of the present invention, the rotary damper 100 is configured as an adjustable damping shaft, and the adjustable damping shaft can adopt common specifications and models on the market. By using the adjustable damping shaft to adjust the damping of the rotary damper 100, the blocking effect of the fixture 30 can be adjusted, thereby achieving the pitch change requirements of different spacings. Of course, the rotary damper 100 and the material dividing member 200 are designed as a detachable connection structure such as a screw connection, and the pitch change of different spacings can also be achieved by replacing the rotary damper 100 with different damping, which is not limited here.

[0028] like Figure 2 In order to expand the function of the jig pitch changing mechanism 10, in another embodiment of the present invention, the jig pitch changing mechanism 10 further includes a counting component 300, which is disposed on the material dividing member 200 to count the number of rotations of the material dividing member 200. The counting component 300 may be an angle encoder, which is connected to the rotating end, and the rotation angle of the rotating end is measured by the background, so as to calculate the number of rotations of the material dividing member 200 and the number of jigs 30 passing through the material dividing member 200, so as to expand the function of the jig pitch changing mechanism 10 and further improve the applicability under various working conditions.

[0029] Figure 3A structural form of the counting component 300 is shown. In this embodiment, the counting component 300 includes: a counting hole 310, one counting hole 310 is arranged on each limit part 210; and a counting sensor 320 is arranged above the material dividing member 200 and opposite to the counting hole 310. The counting holes 310 on each limit part 210 are all on the same circumference. The counting sensor 320 can be an optical fiber sensor, which can be arranged just above the counting hole 310. Whenever a counting hole 310 passes below the optical fiber sensor, the measurement data of the optical fiber sensor changes once. The background can calculate the number of data changes to determine the number of rotations of the material dividing member 200.

[0030] like Figure 2 In one embodiment of the present invention, the jig pitch changing mechanism 10 further includes a stopper assembly 400, which is disposed on one side of the material dividing member 200 to block or release the material dividing member 200. By providing the stopper assembly 400, when the downstream does not need to flow through the jig 30, the jig 30 can be blocked upstream by simply blocking the rotation of the material dividing member 200 through the stopper assembly 400, thereby meeting the use requirements under more working conditions.

[0031] Figure 3 A structural form of the stopper assembly 400 is shown. In this embodiment, the stopper assembly 400 includes: a telescopic member 410, which is arranged on one side of the material dividing member 200, and the telescopic member 410 has a telescopic end that moves close to or away from the material dividing member 200; a blocking member 420, which is arranged at the telescopic end, and the blocking member 420 abuts against or disengages from the side of the material dividing member 200 under the drive of the telescopic end, thereby blocking or releasing the material dividing member 200. Among them, the telescopic member 410 can be a device such as a cylinder, and the telescopic end is telescoped toward one side of the material dividing member 200. The blocking member 420 can be a block structure with a size smaller than the two limiting parts 210. When blocking, the telescopic end drives the blocking member 420 to extend between the two limiting parts 210, and the rotation of the material dividing member 200 can be limited by the limiting of the blocking member 420; when releasing, it is only necessary to drive the blocking member 420 to be pulled out from between the two limiting parts 210.

[0032] like Figure 3In another embodiment of the present invention, the jig distance changing mechanism 10 further includes a bracket 500, which is used to connect with the conveyor line 20, and the fixed end is movably connected with the bracket 500 to approach or move away from the conveyor line 20; wherein, an oblong hole may be provided on the bracket 500, and the oblong hole may extend in a direction perpendicular to the conveyor line 20, and the fixed end may be fastened to the oblong hole by a screw, and when adjustment is required, it is only necessary to loosen the screw and adjust the fixed end along the extension direction of the oblong hole; in order to prevent the jig 30 from directly passing through the jig distance changing mechanism 10 and reaching the downstream, the minimum size of the adapted jig 30 needs to be larger than the distance from the side wall of the conveyor line 20 away from the material dividing piece 200 to the limit portion 210, and the present scheme adjusts the above-mentioned distance so that the jig distance changing mechanism 10 can adapt to jigs 30 of more sizes, thereby further improving the versatility.

[0033] The present invention also proposes a conveying device, which includes a conveying line 20 and a jig distance changing mechanism 10. The jig distance changing mechanism 10 is arranged on one side of the conveying line 20. The specific structure of the jig distance changing mechanism 10 refers to the above embodiment. Since the conveying device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0034] like Figure 1 In another embodiment of the present invention, at least two conveyor lines 20 are provided, and at least two conveyor lines 20 are provided in parallel. At least one jig distance changing mechanism 10 is provided corresponding to each conveyor line 20, and a communication port is provided between every two adjacent conveyor lines 20, and the communication port is provided upstream of the jig distance changing mechanism 10; Figure 1 The specific structural form of this embodiment is shown in Figure 1 In the embodiment, when the jig pitch changing mechanism 10 on the upper conveyor line 20 is locked, the jig 30 will be accumulated upstream of the jig pitch changing mechanism 10 until the jig 30 is accumulated at the connecting port between the two conveyor lines 20. Then, the jig 30 flowing down from the upstream can be diverted from the connecting port to the conveyor line 20 below. In order to ensure smooth diversion, a guiding inclined plate can be set at the connecting port to guide the jig 30 to the conveyor line 20 below, so as to realize the diversion of the jig 30. When the jig pitch changing mechanism 10 on the upper conveyor line 20 is unlocked, the jig 30 can continue to be transported along the upper conveyor line 20. Through the above structural design, various working conditions such as the kicking out of NG products on the production line or the alternating passage of jigs 30 on multiple conveyor lines 20 can be met, further improving the versatility of the conveying device. Of course, the number of conveyor lines 20 can be set to be more, which can be achieved by adopting the above structure, which will not be repeated here.

[0035] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
